350g rotating tank

Awesome idea indeed, but somehow I feel that is totally out of place. And the 'major' purposes that he mentioned:

1)The house is not big enough for a 5 feet round tank to sit in the middle of the room, so the rotation will slowly bring out the "back" of the tank to the viewer.

2)It was designed to mimic the angles of the sunlight from day to night and vice versa

3)The tank will rotate while the light is stationary thus making a lighting effect not to stay stationary and minimize fix directional growth of some SPS.

I don't believe any of these justifications.

Here is another question: How does he acclimate the fish and coral? Hold the bag in his hands and go round and round? (j/k).

I'm very much old school.

It's an interesting tank concept. It's obviously something that you are not going to see everyday.

Yet, at the same time, I feel when you build an exotic looking tank, you take away from the star attractions, which are the fish, corals, and livestock.

Personally, I'd rather have a 350gal rectangular tank, but that's just me.

Judging from the weight and the statements of mimicing natural and varied lighting for the corals, I'm betting that sucker doesn't move as fast we we're all thinking (*like fast enough to make more than one revolution every hour)

But I agree, I'd far rather a 350 rectangle or a wall installation- more room for large tangs to swim!

Anything more then TWO rotation per DAY (or more precisely one per lighting period) will not mimic natural. Problem is that, from the pics of his setup, this is not what happens - the whole surfaces is pretty much uniformly illuminated all the time, so, he is not mimicking anything.

As for round vs rectangular base shape, it is hard to say what is more natural or optimal. Rectangular shape would definitively occupy less "room space", and would be more optimal for accompanying support system (sumps, fuge, plumbing, pumps, skimmers, etc) if positioned and incorporated along the walls. If positioned really in the middle of the room with no contact with any wall surfaces or other furniture, round would be probably more functional and aesthetically pleasing. As for what setup would fish prefer, it highly depends on the type of the fish and the type of the coral reef that you are trying to achieve. If it is a central rock with the swimming space around, them round tank would certainly be more appropriate. If it is a rock wall with plato, then rectangular would be more appropriate. If you have big and/or fast swimmers, then round would probably be better. Also, it would probably be easier to achieve more random turbulent flow with the rectangular then round shape.
